HENRY L. HASKELL, F LUDINGTQN, MICHIGAN.

. DUST-GUARD FOR CAR JOURNAL-BOXES.

Be it known that I, HENRY L. I-InsxnLL,a

. citizen of the United States, residing at Ludington, Michigan, have invented certain First, to provide an improved dust guard new and useful Improvements in Dust- Guards for Car Journal-Boxes, of which the following is a specification.

This invention relates to improvements in dust guards for car journal boxes.

The main objects'of this invention are:

for car journal boxes which is free to ex- I pand uniformly. Second, toprovide an improved dust guard which-is simple in its parts and the partsv are easily assembled.

Third, to provide in a dust guard an im proved seat closure. 7

Further objects, and objects relating to structural details, will definitely appear from the detailed description-to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims;

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a detail longitudinal section through an axle box having my improved dust guard therein, the axle and its journal being shown in full lines. II is a vertical section through my improved dust guard taken on a line corresponding to line 22 of Fig. I. Fig. III is an enlarged de tail section on a line corresponding to line 3-3 of Fig. II, showing the arrangement ofthe joint or dowel pin 11. Fig. IV is a horizontal section on a line corresponding to 7 line H of Fig. II. Fig. V is an enlarged detail section on a line corresponding to line 55 of Fig. II, showing the shape of the joint groove. Fig. V1 is a detail view show ing, the beveled sections. 7 1

In thedrawings,'similar numerals of reference refer to similar parts. throughout the several views, and the sectional views are takenlooking in the direction of the little arrows at the ends of the section lines.

journal box?) isof the usual'or any desired construction and is provided with a journal bearing 4. The box is provided with a slotlike seat 5 adapted to receive the dust guard.

' My improved dust guard is formed of segmental sections or members, the structure illustrated consisting of 6, 6, 7 and 8, the sections or members 6, 6, being the side members, and the section 7 the bottom and the section the'top. These members are joined by "radial tongue and groove joints, the tongues belng on the top and bottom 1nembers, while the grooves 10 are in the side members.

The dowel or joint pins 11 are arranged at right anglesto the planes of the joints. These dowel or joint pins are arranged in countersunk holes 12 in one member to en- In the structure shown, nails are used for the dowelpins. The springs 13 are arranged on the dowel pins to engage the heads thereof, the washers l-fl being arranged in the bottom of the countersinks to form rests, for the inner ends of the springs. This provides a connection which permits the guard to expand uniformly in four directions.

, The guard sections are provided with grooves v15 for the sectional gasket 16. The

gasket sections are provided with beveled joints, as clearly appears-in Fig. VI, so that the asket remains continuous, even when the ust guard is expanded. The bottom of in cross section, so that the gasket bears at its center.

The closure member 17 1s wedge-shaped to fit into. the dust guard slot 5, and is mounted on the top guard member 8 by means of the blade springs 18, there being a pair of these springs, the springs being slotted at 19 to receive the pins 20 on the closure member. Straps 21 connect the ends of the closure member with the top guard V the groove 15 is preferably curved outwardly forl'mly and readily conforms itself to the ax e.

I have not attempted to illustrate or describe various modifications which I contemplate, as such modifications will be readily understood by those skilled in the art to which this invention relates from'the disclosure made.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1.. A dust guard comprising four segmental guard membe'rs having radial tongue and groove joints, the tongues being on the top and bottom members and the grooves in the side members; joint pins arranged in countersunk holes in the top and bottom guard members to engage the said members,

said pins being arranged at right angles to the planes of the joints; a wedge shaped closure member, longitudinally slotted blade springs mounted on the top guard member; pins on said closure member engaging said slots and straps connecting the ends of said closure member to said guard member. 7

2. A dust guard comprising segmental guard members having-radial tongue and groove joints; joint pins connecting adjacent members, said joint-pins being arranged at right angles tothe planes of the joints, at least one of each pair joined being in sliding engagement with the pin; springs arranged on said pins; a closure member; longitudinally slotted springs mounted on one of said guard members; pins onsaid closure member engaging said slot; and straps connecting the ends of said closure member with the said guard member.

'3. A dust guard comprising four segmental guard members having radial interlocking tongue and groove joints, the tongues being on the top and bottom members and the grooves in the side members, said guard members being provided with gasket grooves in their inner edges; headed pins arranged in countersunk holes in the top and bottom guard members to engage the side members,

said pins being arranged at right angles to 'the planes of the joints; springs arranged on saidpins to engage the heads thereof; and; a sectional gasket arranged in the fgroovesof said guard members, the gasket sectionsbeing provided with beveled joints.

4. A dust guard comprising four substantially equal complementary segmental members having radially disposed interlocking tongue and groove joints, the tongues being on one opposed pair of members and v the grooves on the other opposed pair,-said members being grooved on their inner edges .to provide a gasket seat, pins arranged at right angles to the planes of the'joints-in counter sunk holesinthe tongued guard a members to extend through the tongues and driven into the bottoms of the grooves'of the other pair of guard members, said IHGIIlping joints arranged so that the gasket joints do not coincide with but are -nearthe guard member joints whereby the guard member joints are lapped by the gasket sections. 7

5. A dust guard comprising four substan tially equal complementary segmental members having radially disposed interlocking tongue andgroove joints, the tongues being on one opposed pair of members and the grooves on the other opposed pair, pins arranged at right angles to the planes ofthe joints in counter sunk holes in'the tongued guard members to extend through the tongues and driven into the bottoms ofthe grooves of the other pair of guard 'members, said members being supported agalnst relative movement longitudinally of the joints by said joint pins, and springs arranged on said pins in said counter sinks.

6. A dust guard comprising substantially equal complementary segmental members fhaving'radially disposed interlocking tongue and groove joints, said members belng grooved on their lnner'edgesto provide a gasket seat, pins connecting adjacent members and arranged at right anglesf-to the planes of the j oints,one member of each pair of members joined being in sliding. engagement with the pins, said members being supported against relative movement longitudinallyof the joints by said joint pins, and

a gasket sectioned to correspond .7 to the guard members, the sections being provided with beveled lapping joints arranged so that the gasket joints do not coincide with but are near the guard member joints whereby the guard member joints are lapped by the gasket sections.
